UNITED STATES PATENT,

JOHNJFI. SAUNDERSON, OF TRENTON, NEYV JERSEY.

CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 288,868, dated November 20, 1883. Application filed J'unofl, 1883. (N0 model.)

To all whom, it may concern Be itknown that I, JOHN H. SAUNDERSON, a citizen of the United States of America, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Carburetors; and I do hereby declare'the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and toletters or figures of reference marked thereon,which form a part of this specification.

This invention relates to certain new and useful improvements in carburetors, and the same may be used either for enriching gas or carbnreting air; and my invention consists in the construction and combination of the parts which constitute the carburetor, as will be hereinafter more fully setforth, and pointed out in the claims.

In the annexed drawings, which illustrate my invention, Figure 1 is a vertical section. Figs. 2, 3, and at are transverse sections taken on the line w y z of Fig. 1. (Fig. 5 is an enlarged detailed view of the regulating-valve, and Fig. 6 is an enlarged sectional view.

A represents a tank,- which is made of copper, leaded tin, or other non-corrosive mate. rial, and is divided into two compartments, A and A", by apartition, a, of the same kind of material as is used for the construction of the body of the tank. The upper portion of this tank A is used as a reservoir for hydrocarbon or other suitable oil, and is of a capacity equal to about one-half of the lower compartment, Aiwhich is utilized as a generator, and is filled with a finely-prepared packing of absorbent or porous material, as excelsior.

The partition (4, between the compartments of the tank, is provided with three openings. In the larger of these openings is secured a pipe, B,which is secured to the bottom of the tank, and is perforated at its lower end adjacent thereto.

The pipe I), which is located adjacent to the tube or pipe 13, which contains the float, is tightly'secured to the partition (I, and also to the bottom of the tank, the lower end of this pipe being open. This pipe may be provided with a suitable pump or other means for removing the residuum which may collect in the lower portion of the compartment A The pipe B, which is open at its lower end, M

is provided with a float, C, which is provided with arod, 0, attached to the pivoted connecting-bar d, as shown in Fig. 5. This connect ingbar d is also attached to the valve-rod c, to the lower end of which is attached a suit able valve, as shown. This valve-rod a and valve are secured within a downwardly-projecting-pipe, B, which is attached to the pipe B. These pipes are connected to each other,

and are provided with a suitable cover.

To the under portion of the partition A, surrounding the perforation d, is apipe, D,which has connected thereto suitable extending arms, D, with open ends, and short perforated arms d. These arms project or radiate from the center of the upper part of the compartment A To the upper part of the tank or vessel A, over three openings formed therein, are socured stop-cocks and a plug with a movable cap. This plug is for the purpose of testing the depth of the oil in the compartment A, which may be done by inserting arod into the compartment through this opening when the cap is removed.

The two stop-cocks are intended to be used when it is desirable to fill the compartment A, it being desirable to have two, as one will be used as a vent when the oil is poured into the compartment through the other.

To the side wall of the lower compartment, A, are secured three or more troughs, as shown at E E E These troughs gradually increase in size, the upper one beingthe smallest, which projects inwardly sufficiently to be under the open ends of the pipes D, and as the next lower trough is larger than the upper one it will project beyond the edge of the same.

Within the center of the compartment A is 9 5 secured a suitable open support or standard, within which are placed three or more dishes or receptacles having perforated bottoms. These receptacles are indicated by the letters F F F".

The lower compartment, A is provided at its upper portion, near the partition a, with a gas or air inlet pipe, G, which partly encircles the inner wall on its downward course toward the bottom of the chamber, so as to lie under the lower trough, E, from whence it encircles the inner wall of the tank, and at a suitable point it is connected by an upright pipe to another similartube which extends under the next trough,'E. The pipes which extend under the trough hereinbefore described are perforated, so that the gas or air will pass through the same.

The upper part of the compartment or generator A is provided with an outlet-tube, H, the inner side of which may be covered with a suitable screen.

By referring to the annexed drawings, Fig.

5, it will be noticed that above the pipe D, which connects the compartments, the tube B is perforated, and is provided with a spacefor the operation of the valve, the perforation being above the valve-seat, and the stem of the valve operates in a suitable packing, so that the oil in the chamber A cannot siphon .through the pipes 13 B into the lower compartment. This siphoning may also be avoided by extending the pipes which contain the float and valve above the top of the tank.

The operation of my invent-ion may be described as follows: Vhen the hydrocarbon or other oil is placed in the receptacle A, by the means hereinbefore described, it will enter and pass out through the end of the pipe I) and the perforated pi pe d, and will flow into the trough E, and when said trough is filled the overflow will be caught by the troughs which are under the same, and the oil which passes through the perforated pipes (1 will descend centrally and be retarded and diffused by the vessels F F F, which are supported centrally within the lower chamber. By this means the porous or absorbent material with which the receptacle A is packed will be thoroughly saturated, and when the oil begins to collect in the bottom of the tank or compartment A it will raise the float O and cut off the supply by closing the valve, and as the oil is evaporated the float will fall and raise the valve, so as to allow the new supplyto enceases ter, as has been hereinbefore described. By means of the troughs E E E a supply of oil is held within the tank, which will be absorbed by the packing, and will act as a continuous supply for that which is carried off by evaporation. The air or gas which it is desired to enrich enters the generator through the inlet pipe G under a suitable pressure, and it descends to the lower part of the tank A and passes into the oil through the perforated pipes, which are located under the troughs. This air or gas passes through the saturated packing to the outlet-tube, and is greatly enriched, owing to the large amount of carbon which it takes up, and which passes off with the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gas enriching or generating chamber -providedwith a packing of absorbent material, and means for automatically regulating a supply of oil thereto, the pipe D, connected to the regulating means, and perforated pipe cl, said pipe extending over suitable troughs, constructed as described, and perforated ves sel held centrally within said receptacle, and inlet and outlet pipes, substantially as described, and for the purpose set forth.

2. In a carbureting apparatus, the combina .tion of the following elements, to wit: an oil-receptacle located above a chamber filled with absorbent material, and connected thereto by an automatic supply, the pipe D (1, located in the upper part of the chamber containing the packing, the series of troughs increasing in size toward the base of the receptacle, and suspended vessel with perforated bottom supported centrally within said chamber, and an inlet-pipe en circling said chamber under the trough, and

exit at the upper part of said vessel, the parts being organized and combined substantially as shown. and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
